“…The fine structure splittings for the 5s2np2P1/2,3/2 doublet (Table 1) were obtained by counting and interpolating the FSR of the 250MHz interferometer and agree well with recently published data [1][2][3]. They are in complete accordance with the semi-empirical hydrogenic relation…”

“…The laser wavelength setting was controlled by a 1 mgrating-spectrometer and the wavelength reading of a 2-meter. The identification of the Rydberg levels was made by comparing the wavelength and the fine structure splitting in our records with the published values of Neijzen and D/3nszelmann [1][2][3] 3. Results Figure 2 shows the two-photon signal from the transition 5p2P3/2-3tp2~L2,3/2.…”

High resolution spectroscopy of rydberg states in indium I

Two-photon laser spectroscopy in a dense indium vapour allowed to investigate np 2P~/2,3/2 states (n=27-35) for ~3, ~15in with a thermionic diode. Precise data on the fine structure splitting of these states and the isotope shift of the two photon transitions have been obtained. The fine structure splitting shows a hydrogenic behaviour. By using the result of our isotope shift measurement in combination with literature values, level isotope shifts with reference to the ionization limit are deduced and analysed with respect to the different contributions.

“…9 Their results form the basis for the 4s 2 nl levels in the present compilation. By using laser spectroscopic techniques Neijzen and Dönszelmann 35 measured the wavelength of the 4p 2 P°1 /2 -5s 2 S 1/2 resonance transition as 4032.984 ± 0.001 Å; we adopt this wavelength for the present compilation. These authors 35 also used stepwise excitation with two pulsed dye lasers to measure wavelengths of the 5s 2 S 1/2np 2 P°1 /2,3/2 transitions in the region between n = 20 and n = 56 with an uncertainty of ±0.002 Å. Neijzen and Dönszelmann 36 also measured the parity-forbidden transitions 5s 2 S 1/2nd 2 D 3/2,5/2 from n = 19-34.…”

The energy levels and spectral lines of gallium atom in all stages of ionization have been compiled. Experimental data on spectral lines and energy levels exist for spectra Ga I through Ga VII, Ga XIII through Ga XXVI, and Ga XXX. For Li-like Ga XXIX through H-like Ga XXXI, theoretical data on energy levels and line wavelengths are compiled. For Ga I, Ga II, and Ga III we include radiative probabilities of electric-dipole transitions where available. For Ga XV through Ga XX, Ga XXIII through Ga XXVI, and Ga XXX, radiative probabilities of magnetic-dipole and electric-quadrupole transitions are included. The ground state configuration and term and a value of ionization energy are included for each ion.

“…3 we plotted literature values [2,4] of the quantum defect together with our new values for the ZS series as a function of the principal quantum number n. We normalized the quantum defect of the literature values and of our values by using 48387.634 cm-1 as the value for the ionization limit [5]. Apart from core effects for the lowest n values the function is a straight horizontal line within the error limits, indicating that the series is not or negligibly perturbed.…”

“…Figure 2b shows the results of a scan around n=25. The term values were determined by measuring the distance in frequency of the 2S and 2D peaks to the known 2p series [5] in the presence of a small electric field during excitation.…”
